  • Patent number: 11177725
    Abstract: Provided is an IPM motor that is strong and has high output. An IPM motor has a rotor that includes a rotor core as a laminate of a plurality of metal foil pieces made of a soft magnetic material that are stacked in a direction of a rotation axis of the rotor. The rotor core has a plurality of through-holes that penetrates through the rotor core in the direction of the rotation axis, the plurality of through-holes including through-holes embedding magnets. The rotor core includes inner bridges and outer bridges. At least one of the inner bridges and the outer bridges of the rotor core is made of an amorphous soft magnetic material, and other parts are made of a nanocrystal soft magnetic material.
    Type: Grant

  • Patent number: 10892089
    Abstract: The present disclosure provides a method for producing a magnetic component that enables efficient processing of an amorphous soft magnetic material or a nanocrystalline soft magnetic material. The method for producing a magnetic component comprising an amorphous soft magnetic material or nanocrystalline soft magnetic material comprises: a step of preparing a stacked body comprising a plurality of plate-shaped amorphous soft magnetic materials or nanocrystalline soft magnetic materials; a step of heating at least a portion of shearing in the stacked body to a temperature equal to or higher than the crystallization temperature of the soft magnetic materials; and a step of shearing the stacked body at the portion of shearing after the step of heating.
